IMPORTANT NOTES
Power Supply
Do not connect this unit to same electrical outlet that is being used by an
electrical appliance that is controlled by an inverter (such as a refrigerator,
washing machine, microwave oven, or air conditioner), or that contains
a motor. Depending on the way in which the electrical appliance is used,
power supply noise may cause this unit to malfunction or may produce
audible noise. If it is not practical to use a separate electrical outlet,
connect a power supply noise lter between this unit and the electrical
outlet.
The AC adaptor will begin to generate heat after long hours of consecutive
use. This is normal, and is not a cause for concern.
Before connecting this unit to other devices, turn o the power to all units.
This will help prevent malfunctions and/or damage to speakers or other
devices.
Placement
Using the unit near power ampliers (or other equipment containing large
power transformers) may induce hum. To alleviate the problem, change
the orientation of this unit; or move it farther away from the source of
interference.
This device may interfere with radio and television reception. Do not use
this device in the vicinity of such receivers.
Noise may be produced if wireless communications devices, such as
cell phones, are operated in the vicinity of this unit. Such noise could
occur when receiving or initiating a call, or while conversing. Should you
experience such problems, you should relocate such wireless devices so
they are at a greater distance from this unit, or switch them o.
Do not expose the unit to direct sunlight, place it near devices that
radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to
temperature extremes. Also, do not allow lighting devices that normally
are used while their light source is very close to the unit (such as a piano
light), or powerful spotlights to shine upon the same area of the unit for
extended periods of time. Excessive heat can deform or discolor the unit.
When moved from one location to another where the temperature and/or
humidity is very dierent, water droplets (condensation) may form inside
the unit. Damage or malfunction may result if you attempt to use the unit
in this condition. Therefore, before using the unit, you must allow it to
stand for several hours, until the condensation has completely evaporated.
Do not allow rubber, vinyl, or similar materials to remain on this unit for
long periods of time. Such objects can discolor or otherwise harmfully
aect the nish.
Do not allow objects to remain on top of the keyboard. This can be the
cause of malfunction, such as keys ceasing to produce sound.
Do not paste stickers, decals, or the like to this instrument. Peeling such
matter o the instrument may damage the exterior nish.
Depending on the material and temperature of the surface on which you
place the unit, its rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth under the rubber feet to prevent this
from happening. If you do so, please make sure that the unit will not slip or
move accidentally.
Do not put anything that contains water (e.g., ower vases) on this unit.
Also, avoid the use of insecticides, perfumes, alcohol, nail polish, spray
cans, etc., near the unit. Swiftly wipe away any liquid that spills on the unit
using a dry, soft cloth.
Maintenance
To clean the unit, use a dry, soft cloth; or one that is slightly dampened. Try
to wipe the entire surface using an equal amount of strength. Rubbing too
hard in the same area can damage the nish.
Never use benzine, thinners, alcohol or solvents of any kind, to avoid the
possibility of discoloration and/or deformation.
Repairs and Data
Please be aware that all data contained in the unit’s memory may be lost
when the unit is sent for repairs. Important data should always be backed
up USB memories, or written down on paper (when possible). During
repairs, due care is taken to avoid the loss of data. However, in certain
cases (such as when circuitry related to memory itself is out of order), we
regret that it may not be possible to restore the data, and Roland assumes
no liability concerning such loss of data.
Additional Precautions
Please be aware that the contents of memory can be irretrievably lost as
a result of a malfunction, or the improper operation of the unit. To protect
yourself against the risk of loosing important data, we recommend that
you periodically save a backup copy of important data you have stored in
the unit’s memory on USB memories.
Unfortunately, it may be impossible to restore the contents of data that
was stored in the unit’s memory or USB memories once it has been lost.
Roland Corporation assumes no liability concerning such loss of data.
Use a reasonable amount of care when using the unit’s buttons, sliders, or
other controls; and when using its jacks and connectors. Rough handling
can lead to malfunctions.
Never strike or apply strong pressure to the display.
When connecting / disconnecting all cables, grasp the connector itself—
never pull on the cable. This way you will avoid causing shorts, or damage
to the cable’s internal elements.
To avoid disturbing your neighbors, try to keep the unit’s volume at
reasonable levels. You may prefer to use headphones, so you do not need
to be concerned about those around you.
The sound of keys being struck and vibrations produced by playing an
instrument can be transmitted through a oor or wall to an unexpected
extent. In particular, when using headphones, please take care not to
cause annoyance to others nearby.
When you need to transport the unit, package it in the box (including
padding) that it came in, if possible. Otherwise, you will need to use
equivalent packaging materials.
Do not apply undue force to the music rest while it is in use.
Use only the specied expression pedal (EV-7; sold separately). By
connecting any other expression pedals, you risk causing malfunction
and/or damage to the unit.
Some connection cables contain resistors. Do not use cables that
incorporate resistors for connecting to this unit. The use of such cables
can cause the sound level to be extremely low, or impossible to hear. For
information on cable specications, contact the manufacturer of the cable.
The usable range of D Beam controller will become extremely small when
used under strong direct sunlight. Please be aware of this when using the
D Beam controller outside.
The sensitivity of the D Beam controller will change depending on the
amount of light in the vicinity of the unit. If it does not function as you
expect, adjust the sensitivity as appropriate for the brightness of your
location.
When moving the ATELIER, take care not to damage the keyboard or the
harmonic bars.
